What is the name of the pop-up window in the Experience Editor used for editing non-inline editable fields?

The pop-up window in the Experience Editor utilized for editing non-inline editable fields is referred to as the Field Editor. This tool provides a focused interface for content authors and editors to modify specific fields in detail, rather than making changes directly on the page. It is especially beneficial for fields that do not support inline editing due to their complexity or data type.

The functionality of the Field Editor allows for a more structured editing experience, giving users the ability to interact with various field types, such as rich text fields, media fields, and other content types that may require a distinct editing approach. This streamlines the editing process and ensures that content creators can make precise changes without affecting the overall layout immediately seen in the Experience Editor.

Other options like the Content Editor and Item Editor refer to different areas or functionalities within Sitecore used for managing content and items but do not specifically denote the pop-up feature for non-inline editing. The Editor Panel is also not a recognized term within the context of Sitecore's editing capabilities in the Experience Editor. Hence, the Field Editor is the correct choice due to its specific role in supporting content editing for fields that are not editable directly on the page.
